So, I got a kegging setup from for Christmas .. I don't have much space at all for it, and opted for a 20oz CO2 tank, I can fill it at Dick's sporting goods for 3.99 near my house.. I used an aluminum adapter that was advertised on here to connect it to a dual gauge regulator..
When I got it hooked up to the keg, closed the valve and went to screw the bottle on, the pressure relief (with the ring on it) starts blowing out CO2 and opening and closing really quick making a buzzing noise and causing the gauges to jump around..
I know it isn't normal - is there anything else I should check ??
